I am fostering a 10 month old male dog who is in all areas a very healthy happy dog. Except, with the exception of his size. Though he is abnormally tall (weighing 82 pounds... most of this is height) he still appears very skinny and when I pet him along his back I can feel his vertebrae when his back arches upwards near the tail. As well I can also feel his ribs when he is standing.

The person who had him before DID NOT neglect him in any way. She is a highly respected person who trains dogs for the sheriffs department. I dont want my post to sound like he was in any way neglected before he came into my care.

I think maybe he has grown too fast, or something, but we will be seeing a vet within the next week to check up on his BMI.

I started supplementing with a can of dog food each day in addition to his Pedigree- Large Breed food. He also is fed vitamins. Is this something most GSD go through during their 'teenage' days and what other foods would be good for putting on weight? I am very new to the breed and feel bad that he is so skinny.
